/* ==========================================================================
   Mouseion 慕识书院 官网样式表
   设计取向：参照国内头部原版阅读机构的成熟官网结构（如厚海阅读）
   - 现代教育机构范式：分段色带（白 / 浅灰 / 深藏青）+ 大号数字 + 卡片组
   - 中英双标：中文大标题 + 全大写英文小标签
   - 主色取品牌深板岩，强调色取品牌金（对应参照站的蓝 + 橙结构）
   - 圆角卡片 + 柔和阴影 + 药丸按钮，信息密度高但层次清晰
   色彩仍来自《慕识书院品牌指导手册》与成长路径海报主色
